The Department of Defense (DoD,[5] USDOD, or DOD) is an executive branch department of the federal government of the United States charged with coordinating and supervising all agencies and functions of the government concerned directly with national security and the United States Armed Forces. The Department is the largest employer in the world,[6] with nearly 1.3 million active duty servicemen and women[a] as of 2016.[7] Adding to its employees are over 826,000 National Guardsmen and Reservists from the four services,[b] and over 742,000 civilians bringing the total to over 2.8 million employees.[1] It is headquartered at the Pentagon in Arlington, Virginia, just outside Washington, D.C. The Department of Defense is headed by the Secretary of Defense, a cabinet-level head who reports directly to the President of the United States. Beneath the Department of Defense are three subordinate military departments: the United States Department of the Army, the United States Department of the Navy, and the United States Department of the Air Force. In addition, four national intelligence services are subordinate to the Department of Defense: the Defense Intelligence Agency (DIA), the National Security Agency
National Security Agency
(NSA), the National Geospatial-Intelligence Agency (NGA), and the National Reconnaissance Office (NRO). Other Defense Agencies include the Defense Advanced Research Projects Agency (DARPA), the Defense Logistics Agency
Defense Logistics Agency
(DLA), the Missile Defense Agency
Missile Defense Agency
(MDA), the Defense Health Agency (DHA), Defense Threat Reduction Agency
Defense Threat Reduction Agency
(DTRA), the Defense Security Service (DSS), and the Pentagon Force Protection Agency
Pentagon Force Protection Agency
(PFPA), all of which are under the command of the Secretary of Defense. Military operations are managed by nine regional or functional Unified combatant commands. The Department of Defense also operates several joint services schools, including the National Defense University
National Defense University
(NDU) and the National War College
National War College
(NWC).

History[edit] See also: National Security Act of 1947
National Security Act of 1947
and History of the United States military The history of the defense of the United States started with the Continental Congress in 1775. The creation of the United States Army was enacted on June 14, 1775.[8] This coincides with the American holiday Flag Day. The Second Continental Congress would charter the United States Navy, on October 13, 1775,[9] and create the United States Marine Corps on November 10, 1775. Today, both the Navy and the Marine Corps are separate military services subordinate to the Department of the Navy.[10] The War Department[edit] Main article: United States Department of War The Preamble of the United States Constitution gave the authority to the federal government to defend its citizens:

We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America. — Constitution of the United States

Upon the seating of the first Congress on March 4, 1789, legislation to create a military defense force stagnated as they focused on other concerns relevant to setting up the new government. President George Washington went to Congress to remind them of their duty to establish a military twice during this time. Finally, on the last day of the session, September 29, 1789, Congress created the War Department, historic forerunner of the Department of Defense.[11][12] The War Department handled naval affairs until Congress created the Navy Department in 1798. The secretaries of each of these departments reported directly to the President as cabinet-level advisors until 1949, when all military departments became subordinate to the Secretary of Defense. National Military Establishment[edit]

President Harry Truman
Harry Truman
signs the National Security Act Amendment of 1949

After the end of World War II, President Harry Truman
Harry Truman
proposed creation of a unified department of national defense. In a special message to Congress on December 19, 1945, the President cited both wasteful military spending and inter-departmental conflicts. Deliberations in Congress went on for months focusing heavily on the role of the military in society and the threat of granting too much military power to the executive.[13] On July 26, 1947, Truman signed the National Security Act of 1947, which set up a unified military command known as the "National Military Establishment", as well as creating the Central Intelligence Agency, the National Security Council, National Security Resources Board, United States Air Force
United States Air Force
(formerly the Army Air Forces) and the Joint Chiefs of Staff. The act placed the National Military Establishment under the control of a single Secretary of Defense.[14][15][16] The National Military Establishment formally began operations on September 18, the day after the Senate confirmed James V. Forrestal
James V. Forrestal
as the first Secretary of Defense.[15] The National Military Establishment was renamed the "Department of Defense" on August 10, 1949 and absorbed the three cabinet level military departments, in an amendment to the original 1947 law.[17] Under the Department of Defense Reorganization Act
Department of Defense Reorganization Act
of 1958 (Pub.L. 85–599), channels of authority within the department were streamlined, while still maintaining the ordinary authority of the Military Departments to organize, train and equip their associated forces. The Act clarified the overall decision-making authority of the Secretary of Defense with respect to these subordinate Military Departments and more clearly defined the operational chain of command over U.S. military forces (created by the military departments) as running from the President to the Secretary of Defense and then to the unified combatant commanders. Also provided in this legislation was a centralized research authority, the Advanced Research Projects Agency, eventually known as DARPA. The act was written and promoted by the Eisenhower administration, and was signed into law August 6, 1958. Organizational structure[edit] Main article: Organizational structure of the United States Department of Defense See also: List of Department of Defense agencies

Department of Defense organizational chart (December 2013)

The Secretary of Defense, appointed by the President with the advice and consent of the Senate, is by federal law (10 U.S.C. § 113) the head of the Department of Defense, "the principal assistant to the President in all matters relating to Department of Defense", and has "authority, direction and control over the Department of Defense". Because the Constitution vests all military authority in Congress and the President, the statutory authority of the Secretary of Defense is derived from their constitutional authorities. Since it is impractical for either Congress or the President to participate in every piece of Department of Defense affairs, the Secretary of Defense, and the Secretary's subordinate officials generally exercise military authority. The Department of Defense is composed of the Office of the Secretary of Defense (OSD), the Joint Chiefs of Staff
Joint Chiefs of Staff
(JCS) and the Joint Staff (JS), Office of the Inspector General (DODIG), the Combatant Commands, the Military Departments (Department of the Army (DA), Department of the Navy (DON) & Department of the Air Force (DAF)), the Defense Agencies and Department of Defense Field Activities, the National Guard Bureau (NGB), and such other offices, agencies, activities, organizations, and commands established or designated by law, or by the President or by the Secretary of Defense. Department of Defense Directive 5100.01 describes the organizational relationships within the Department, and is the foundational issuance for delineating the major functions of the Department. The latest version, signed by former Secretary of Defense Robert Gates
Robert Gates
in December 2010, is the first major re-write since 1987.[18][19] Office of the Secretary of Defense[edit] Main article: Office of the Secretary of Defense

National Intelligence Agencies[edit] Several defense agencies are members of the United States Intelligence Community. These are national-level intelligence services that operate under the jurisdiction of the Department of Defense but simultaneously fall under the authorities of the Director of National Intelligence. They fulfill the requirements of national policy makers and war planners, serve as Combat Support Agencies, and also assist non-Department of Defense intelligence or law enforcement services such as the Central Intelligence Agency
Central Intelligence Agency
and the Federal Bureau of Investigation. The military services each have their own intelligence elements which are distinct from but subject to coordination, by national intelligence agencies under Department of Defense. Department of Defense manages the nation's coordinating authorities and assets in disciplines of signals intelligence, geospatial intelligence, and measurement and signature intelligence, and also builds, launches and operates the Intelligence Community's satellite assets. Department of Defense also has its own human intelligence service, which contributes to the CIA's human intelligence efforts while also focusing on military human intelligence priorities. These agencies are directly overseen by the Undersecretary of Defense for Intelligence.

The Joint Chiefs of Staff
Joint Chiefs of Staff
(JCS) is a body of senior uniformed leaders in the Department of Defense who advise the Secretary of Defense, the Homeland Security Council, the National Security Council and the President on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of the Chairman of the Joint Chiefs of Staff (CJCS), Vice Chairman of the Joint Chiefs of Staff (VCJCS), Senior Enlisted Advisor to the chairman (SEAC), the Military Service Chiefs from the Army, Marine Corps, Navy, and Air Force, in addition to the Chief of National Guard Bureau, all appointed by the President following Senate confirmation.[20] Each of the individual Military Service Chiefs, outside their Joint Chiefs of Staff obligations, works directly for the Secretary of the Military Department concerned, i.e. Secretary of the Army, Secretary of the Navy, and the Secretary of the Air Force.[21][22][23][24] Following the Goldwater-Nichols Act
Goldwater-Nichols Act
in 1986 the Joint Chiefs of Staff do not have operational command authority, neither individually nor collectively, as the chain of command goes from the President to the Secretary of Defense, and from the Secretary of Defense to the Commanders of the Combatant Commands.[25] Goldwater-Nichols also created the office of vice-chairman, and the chairman is now designated as the principal military adviser to the Secretary of Defense, the Homeland Security Council, the National Security Council and to the President.[26] The Joint Staff
Joint Staff
(JS) is a headquarters staff at the Pentagon composed of personnel from all four services that assist the chairman and vice-chairman in discharging their duties, and managed by the Director of the Joint Staff
Joint Staff
(DJS) who is a Lieutenant General or Vice Admiral.[27][28]

Military Departments[edit]

Military Departments of the Department of Defense

Department of the Army 

Department of the Navy 

Department of the Air Force 

There are three Military Departments within the Department of Defense:

the Department of the Army, which the United States Army
United States Army
is organized within. the Department of the Navy, which the United States Navy
United States Navy
and the United States Marine Corps
United States Marine Corps
are organized within. the Department of the Air Force, which the United States Air Force
United States Air Force
is organized within.

The Military Departments are each headed by their own Secretary (i.e., Secretary of the Army, Secretary of the Navy
Secretary of the Navy
and Secretary of the Air Force), appointed by the President, with the advice and consent of the Senate. They have legal authority under Title 10 of the United States Code to conduct all the affairs of their respective departments within which the military services are organized.[29] The Secretaries of the Military Departments are (by law) subordinate to the Secretary of Defense and (by SecDef delegation) to the Deputy Secretary of Defense. The Secretaries of the Military Departments, in turn, normally exercises authority over their forces by delegation through their respective Service Chiefs (i.e., Chief of Staff of the Army, Commandant of the Marine Corps, Chief of Naval Operations, and Chief of Staff of the Air Force) over forces not assigned to a Combatant Command.[30] The Secretaries of the Military Departments and the Service Chiefs do not possess operational command authority over U.S. troops (this power was stripped from them in the Defense Reorganization Act of 1958), and instead the Military Departments are tasked solely with "the training, provision of equipment, and administration of troops."[30] Unified Combatant Commands[edit]

Map of the Department of Defense's geographic commands

A Unified Combatant Command
Unified Combatant Command
is a military command composed of personnel and equipment from at least two Military Departments, which has a broad and continuing mission.[31][32] The Military Departments are responsible for equipping and training the troops to fight, while the Unified Combatant Commands are responsible for actual operational command of military forces.[32] Almost all operational U.S. forces are under the authority of a Unified Command.[30] The Unified Commands are governed by a Unified Command Plan, a frequently updated document (produced by the Department of Defense) which lays out the Command's mission, geographical/functional responsibilities, and force structure.[32] During military operations, the chain of command runs from the President to the Secretary of Defense to the combatant commanders of the Combatant Commands.[30] The United States currently has nine Combatant Commands, organized either on a geographical basis (known as "area of responsibility", AOR) or on a global, functional basis:[33]

U.S. Northern Command (USNORTHCOM) U.S. Southern Command

Budget[edit]

Chart showing growth in U.S. Department of Defense spending 2000–2011

Main article: Military budget of the United States

Defense Spending as a Percent of GDP 1792-2017

Department of Defense spending in 2010 was 4.8% of GDP and accounted for about 45% of budgeted global military spending – more than the next 17 largest militaries combined.[34][35] The Department of Defense accounts for the majority of federal discretionary spending. In FY 2010 the Department of Defense budgeted spending accounted for 21% of the U.S. Federal Budget, and 53% of federal discretionary spending, which represents funds not accounted for by pre-existing obligations.[36] However, this does not include many military-related items that are outside the Defense Department budget, such as nuclear weapons research, maintenance, cleanup, and production, which is in the Department of Energy budget, Veterans Affairs, the Treasury Department's payments in pensions to military retirees and widows and their families, interest on debt incurred in past wars, or State Department financing of foreign arms sales and militarily-related development assistance. Neither does it include defense spending that is not military in nature, such as the Department of Homeland Security, counter-terrorism spending by the FBI, and intelligence-gathering spending by the NSA. In the 2010 United States federal budget, the Department of Defense was allocated a base budget of $533.7 billion, with a further $75.5 billion adjustment in respect of 2009, and $130 billion for overseas contingencies.[37] The subsequent 2010 Department of Defense Financial Report shows the total budgetary resources for fiscal year 2010 were $1.2 trillion.[38] Of these resources, $1.1 trillion were obligated and $994 billion were disbursed, with the remaining resources relating to multi-year modernization projects requiring additional time to procure.[38] After over a decade of non-compliance, Congress has established a deadline of Fiscal year
Fiscal year
2017 for the Department of Defense to achieve audit readiness.[39] In 2015 the allocation for the Department of Defense was $585 billion,[40] the highest level of budgetary resources among all Federal agencies, and this amounts to more than one-half of the annual Federal Expenditures in the United States federal budget discretionary budget.[41] Criticism[edit] 2016 Internal Study Cover Up[edit] In 2015, a Pentagon consulting firm performed an audit on the department of defense's budget. It found that there was $125 billion in wasteful spend that could be saved over the next 5 years without layoffs or reduction in military personnel. In 2016, The Washington Post uncovered that rather than taking the advise of the auditing firm, senior defense officials suppressed and hid the report from the public to avoid political scrutiny.[42] Manipulation of Finances[edit] In June 2016, The Defense Department's Inspector General released a report that stated the United States Army
United States Army
made $6.5 trillion in wrongful adjustments to its accounting entries in 2015.[43] Energy use[edit] Main article: Energy usage of the United States military The Department of Defense was the largest single consumer of energy in the United States in 2006.[44] In FY 2006, the Department used almost 30,000 gigawatt hours (GWH) of electricity, at a cost of almost $2.2 billion. The Department's electricity use would supply enough electricity to power more than 2.6 million average American homes. In electricity consumption, if it were a country, the Department would rank 58th in the world, using slightly less than Denmark
Denmark
and slightly more than Syria
Syria
(CIA World Factbook, 2006).[45] The Department of Defense is responsible for 93% of all US government fuel consumption in 2007 (Department of the Air Force: 52%; Department of the Navy: 33%; Department of the Army: 7%; other Department components: 1%).[45] The Department of Defense uses 4,600,000,000 US gallons (1.7×1010 L) of fuel annually, an average of 12,600,000 US gallons (48,000,000 L) of fuel per day. A large Army division may use about 6,000 US gallons (23,000 L) per day. According to the 2005 CIA World Factbook, if it were a country, the Department of Defense would rank 34th in the world in average daily oil use, coming in just behind Iraq
Iraq
and just ahead of Sweden.[46] The Air Force is the largest user of fuel energy in the federal government. The Air Force uses 10% of the nation's aviation fuel. ( JP-8 accounts for nearly 90% of its fuels.) This fuel usage breaks down as such: 82% jet fuel, 16% facility management and 2% ground vehicle/equipment.[47] Freedom of Information Act processing performance[edit] In the latest Center for Effective Government analysis of 15 federal agencies which receive the most Freedom of Information Act (United States) (FOIA) requests, published in 2015 (using 2012 and 2013 data, the most recent years available), the DoD earned a D− by scoring 61 out of a possible 100 points, i.e. did not earn a satisfactory overall grade. While it had improved from a failing grade in 2013, it still had low scores in processing requests (55%) and their disclosure rules (42%).[48] Related legislation[edit] The organization and functions of the Department of Defense are in Title 10 of the United States Code. Other significant legislation related to the Department of Defense includes:

1947: National Security Act of 1947 1958: Department of Defense Reorganization Act, Pub.L. 85–599 1963: Department of Defense Appropriations Act, Pub.L. 88–149 1963: Military Construction Authorization Act, Pub.L. 88–174 1967: Supplemental Defense Appropriations Act, Pub.L. 90–8 1984: Department of Defense Authorization Act, Pub.L. 98–525 1986: Goldwater-Nichols Act
